Title: Improvements in or relating to trialiphatic hydrocarbyl phosphites
Inventor: HECHENBLEIKNER INGENUIN
IPC: C07F9/142
Filed: 1958-02-10
Abstract: A trialiphatic hydrocarbyl phosphite is obtained by transesterifying a triaryl phosphite with at least 3 mols of a monohydroxy aliphatic hydrocarbon or at least 3 mols of a mixture of monohydroxy aliphatic hydro-carbons per mol of triaryl phosphite in the presence as catalyst of a substance which is sufficiently basic to have a pH of at least 11 in a 0.1 N aqueous solution.  The catalyst is preferably an alkali metal or alkaline earth metal salt of an alcohol or a phenol and is suitably an alkali metal alcoholate formed in situ, from an alcohol and an alkali metal, e.g. sodium, potassium, or lithium.  Specified triaryl phosphites include tri-p-cresyl phosphite, triphenyl phosphite, and tri-o-chloro-phenyl phosphite, and specified aliphatic hydroxy compounds include alkanols and alkenols, e.g. methyl, isobutyl, iso-octyl, lauryl, allyl and oleyl alcohols and buten-2-ol-1.  The alkanol used should preferably have at least 6 carbon atoms and the alkenol should preferably be of even higher molecular weight.  The metal alcoholate or metal phenolate preferably used as catalyst is preferably used in an amount of between 0.001 and 0.20 mol per mol of triaryl phosphite.  The reaction can be carried out at room temperature or below or the mixture can be heated to remove the phenol or product formed. Suitable temperatures are from 0 DEG C. to 180 DEG C. and atmospheric, superatmospheric or subatmospheric pressure can be employed.  A mixture of alcohols can be employed, thus monolauryl distearyl phosphite can be formed by using 2 mols of stearyl alcohol, 1 mol of lauryl alcohol, 1 mol of triphenyl phosphite and 0.02 mol of sodium phenolate and heating the mixture at 10-20 mm. pressure to remove the phenol formed.  Examples are given for the production of (1) tributyl phosphite and some dibutyl phenyl phosphite from triphenyl phosphite and n-butanol in the presence of sodium butylate formed in situ from the alcohol and metallic sodium; (2) triallyl phosphite and some diallyl phenyl phosphite by a similar procedure as in (1); (3) tri-2-ethylhexyl phosphite from triphenyl phosphite and 2-ethyl hexanol using a catalyst formed in situ by adding metallic sodium; (4) trilauryl phosphite, by a procedure as in (3); (5) trimethyl phosphite and some dimethyl phenyl phosphite by a procedure as in (3); and (6) tristearyl phosphite from triphenyl phosphite and stearyl alcohol in the presence of sodium phenolate.  The trialkyl and trialkenyl phosphites may be used as stabilizers for vinyl chloride resins and as lubricant additives.

Title: Means and method for time-sharing multichannel well logging
IPC: E21B47/12
Filed: 1973-01-27
Abstract: 1381235 Well-logging TEXACO DEVELOPMENT CORP 27 Jan 1973 4297/73 Heading G4H Apparatus for providing outputs corresponding to different sensed conditions comprises a transmitter, Fig. 1, responsive to the outputs of, e.g. three sensors to send a data signal E2 Fig. 3, to a receiver, Fig. 2, wherein each cycle of E2 is divided into time-slots T1, T2 and T3-T5 for the transmission of a "collar signal", a sync pulse, and data from the sensors. Clock pulses E1 are used by a control circuit 7 to generate cycle division pulses E3; these cause a commutator 18 to output signals E7- Ell to " collar ", sync pulse and data channels 16-22B during their respective intervals T1- T5. In each data channel 22, the sensed condition is output as a number of pulses which are counted in a counter having a maximum value of 8: during the respective interval T3- T5, these counters count clock pulses E1A until the count of 8 is reached so as to output an " 8's complement " pulse train E25-E25B to a gate 60. The pulse trains, together with " collar " pulses E20 and sync pulse E22, constitute data signal E2.  At the receiver, E2 passes to a separator 105 to extract the sync pulse E33 and the " collar " and data pulses E32 which are applied to storage circuits 114 etc. During intervals T3- T5 (data) and T1 (" collar " between this and next cycle) these circuits are enabled by outputs E38-E41 of a commutator 118, the data pulse being counted by counters having a maximum value of 8. A pulse E34 from delay circuit 109 causes a commutator 120 to enable circuits 114 when they are no longer receiving data pulses so that their counters may count clock pulses E35 until the counters reach their maximum value: this gives rise to outputs E50 50B consisting of a number of pulses equal to the values measured by the sensors. These outputs are fed to integrators 122-122C and thence to recorders 123, 124A. The sensors may be used in a well-logging system, when the conditions relate to the borehole and the earth traversed thereby. They may measure chlorine content, temperature or sonic velocity.
